\nWarning: Be careful, each browser on each platform reacts differently to
\nthose instructions and tests are required to make sure that your Javascript will
\nbehave as expected. Even the browser detection scripts on website such as
\nJavascript.com cannot be considered as working correctly in all situations. <\/div>\n
An easy way to make the $platform<\/code> variable to the PHP code is to
\nrecall the index file with some parameters. This is almost invisible for the
\nvisitor but do not forget to include a $detect<\/code> variable
\n(initialised to true<\/code> if not set) to avoid to enter a loop where the
\nindex file is replaced and replaced again. As soon as the parameter (here
\nplatform) is detected, the $detect<\/code> variable is set to false.
The
\nvariable $platform<\/code> is now available to the index file and therefore
\nto the stylesheet. You can test it using a switch() { case: ; }<\/code>
\nblock and, in our example, increase the font size by 2 in case a Mac based
\nplatform is detected (extracted from stylesheet.css.php<\/code>):\n<\/div>\n

\nThe value of this increment should depend on the font unit that you use (px,
\npt, em, etc.). This increment could also be declared as a new visual parameter
\nto be included in your visual configuration file as:<\/div>\n

<?php
\n
$VISUALS<\/span>[<\/span>0<\/span>][<\/span>'page'<\/span>][<\/span>'fontsize'<\/span>][<\/span>'increment'<\/span>]
